Be it known that I, G O RENNER, a citi- 'zen of the'German Republic, andresidentof 137 Bilker Allee,Dusseldorf, Germany, have invented certainnew and useful Improvements in Flush-Gisterns for which I havefiledapplications in Germany, Mar. 8, 1914;

1919; Sweden, June 5, 1919; France, June 7 1919 Switzerland, July 19,1919 Finland, July 21, 1919; Belgium, July 31, 1919; Gr. Britain, Nov.7, 1919; Italy, May 10, 1920; Luxemburg, Aug. 4, 1920; Holland, Sept.15, 1920; Czechoslovakia, Apr. 23, 1921, of which the following is astatement.

The present invention relates to a flushing cistern, which, when not 1nuse, is free of water, and on which the lock for the lever controllingthe supply and discharge valves is released by a float. The feature ofthe present invention consists in the dischargeaccording to the presentinvention is shown in longitudinal section in Figures 1 and 5,respectively, while Fig. 2 is a plan of a portion of the tank. Fig. 3illustrates the supply valve with a piece of the control lever and ofthe float lever, partly in section, partly in elevation; Fig. 4 is aplan to Fig. 3, Fig. 6 is the lock member incombination with the floatlever and the control lever in side elevation in another position, andFig. 7 is a front elevation thereof; Fig. 8 is a plan of the lockingmember with only a piece of the float lever.

The discharge valve hasthe form of a siphon tube 01. It is provided withtrunnions e which rest in bearings t!) provided on the discharge tubeaof the cistern tank I). When in an upright position this siphon tubebears with its jointing surface a tightly against 7 the mouthof thedischarge tube a. Cast in one piece with said siphon tube (2 is abracket 7, on which rests the control lever g.

This control lever g is pivotally fitted on a pivot on the housing 2' ofthe supply valve and engages with an arm 1 projecting there from into aslot 977} in the valve plug m, to which is fitted a rubber disk m forclosing the supply orifice a.
